Gardner Bender BV208D - Manual (Page 3)

c. Conduit Sizes 2-1/2" to 6"
i.
Items required are the BV26 seal-off body and the
BV24 seal-off (see Figure 5).
ii. Tag-A-Long or bulk nylon pull line and poly-pull
rope are the types of material suitable for 2-1/2" to
6" conduit. A line carrier is required for each type
pull line or poly rope. Maximum pull line size is
PL232 bulk line (see Figure 6).
Maintenance After Vacuuming Dirt and
Water
1. Release the latches securing the top and center
sections together.
2. Remove the filter bag from the bottom tool storage
section. Slide the filter bag onto the intake canister
located on the bottom of the motor. The filter bag
prevents dust from entering the motor. Dust and dirt
will damage the motor and cause premature failure.
3. Clean the filter bag by shaking off the excess dirt.
Store the clean bag in the lower storage compartment.
4. The Blo-Vac is equipped with a ball float to prevent
water from entering the motor. If the ball float seals the
motor inlet, the motor will sound different from usual.
Immediately shut the unit off. Empty the recovery
section and check the inlet screen for dirt and lint.
Clean the screen and reassemble the Blo-Vac
sections.
Line Carriers
Foam Line Carriers
These are the original line carriers
made of high density poly-foam. As
the line carrier travels through the
conduit it provides a swabbing action
cleaning out water and loose debris.
These carriers have a hook on one end for convenient
attachment of a TAG-A-LONG line package and an eye on
the other end for attachment of pull line. Foam line carriers
are available for 1/2" - 6" conduit sizes (See Figure 7).
The Inflatables® Line Carriers
This patented device has less
friction in the conduit and runs faster
than the foam line carrier. The
flexible nature of the inflatable
carrier allows it to conform to the
conduit diameter. It can pass over
local obstructions that would stop a
foam line carrier. This device can be
vacuumed or blown through conduit. They are
manufactured of tough durable nylon material and are
available in four models covering 3/4"-6" conduit sizes
(see Figure 8).
Missile Line Carriers
Molded of polyethylene plastic,
these low friction carriers offer the
highest speed of the three types of
carriers. These carriers were
developed for the CO2 Electric
Blowers and Blo-Vac systems for
use in long and large conduit runs.
If the line carrier encounters a
blockage, the slotted skirt allows the carrier to be pulled
out past joints or steps in the conduit. A hard tug on the
pull line will cause the petals to turn inside out allowing for
easy withdrawal. They are available in 2"-6" conduit sizes
(see Figure 9).
Pull Line
Power Saver™ Line Package
A combination carrier and pull line,
this is the easiest and most
versatile line that can be installed in
conduit. The self contained nylon
line package comes in different
sizes for 1/2", 3/4", and 1" conduit.
It dispenses a line as the package
is blown through the conduit (see Figure 10).
Tag-A-Long™ Line Package
This package is designed for longer
runs and must be used with a line
carrier. The increased package
diameter and length prevents the
package from passing freely through
or around bends in conduit less than
1-1/2". Once attached to the line carrier,
the Tag-A-Long line package
function and operation is similar to that of the
Power Saver (see Figure 11).
